The 0.5 seemed to be an often over looked style, and sprung forth from a merger of the 0.2 and the 0.4.
The 0.5 became and extension of the 0.4, adding the shielding to the popular 0.4 style for added peripheral protection.

an often forgotten style, being looking for these but when they do come up-prices are crazy. the extra detail/fins around the orbitals compared to the 0.4 but them so desirable.
more desirable i think than the 0.3 due to the fact they are so hard to find

As an extension of the 0.4, the 0.5 added fins to the lens, giving it a unique shape. I only wish I could wear these, but due to the prices they pull now, it's not realistic.

yea these are really nice, i am pleased, the detail on the lense is really interesting. I like how there is a little extra shield around the lense and how the lens is sandblasted by the nose
